Use the Coverage section to specify the combinations
of environmental attributes to test.
- Minimal: Ensures that each selected attribute value is covered
at least once, with no attempt to cover specific combinations of attributes.
- Medium, pair-wise interaction: Ensures that each combination of
paired attribute values is covered at least once.
- Large, three-way interaction: Ensures that each three-way combination
of attribute values is covered at least once.
Changing from minimal to pair-wise interaction and
from pair-wise to three-way interaction creates proportionately more test
execution records.
